...New SHORT TERM...

.SHORT TERM...
(Today and tonight)
Issued at 202 AM CDT Sun Jul 11 2021

Line of strong to severe showers and thunderstorms south of the
Red River Valley at 130 AM will be moving into Haskell and
Throckmorton around 330 AM...and the I-20 corridor including
Abilene between 530 and 630 AM. While the line of storms is
expected to weaken, some storms may still be capable of damaging
winds to 60 mph and penny size hail through daybreak.

While the short range models indicate the storms diminishing early
this morning, additional storm development is possible by mid
afternoon with additional heating, and as a weak cold front moves
into the Concho Valley and Heartland and dissipates. Surface based
CAPES increase to 1500-2000 J/KG and MUCAPES 2000-2800 J/KG this
afternoon, so there should enough instability for severe storms. SPC
has a marginal risk of severe storms across much of West Central
Texas north of I-10, with a slight risk over Callahan, Runnels,
Coleman, Brown Counties today and tonight.

Highs will likely be a couple degrees cooler due to clouds and
storms, but still warm in the 90 to 93 degree range. Lows tonight
will be near 70.

&&

.LONG TERM...
(Monday through Saturday)
Issued at 138 AM CDT Sun Jul 11 2021

Anything left from the frontal boundary that is expected to move
into central Texas on Sunday should wash out for Monday. But, any
residual outflows from earlier precipitation may provide a focus
for a few storms across the Concho Valley and I-10 corridor on
Monday, mainly in the afternoon. At this point, storm coverage
should be fairly low and will not likely be severe. Otherwise,
highs should reach the upper 80s to around 90 areawide. Stratus
and convective debris may hold down high temperatures in a few
places as well.

As we get into Tuesday and beyond, we'll start to see a slight
pattern change set up.  The upper ridge out west will continue to
wobble around and fluctuate, while otherwise staying centered over
the Desert Southwest.  Global models show a series of 500mb
shortwave troughs traversing the northern and central US through
much of the week. Despite some instability during this time period,
there is no real good focus for convection each day, save for an
isolated afternoon pop-up shower.  As a result, skies will gradually
be sunnier with fewer clouds and rain chances, along with steady
south flow at the surface.  This should lead to high temperatures
reaching closer to the mid 90s, which is right around our normal for
mid July. Over the weekend, global models suggest a stronger
shortwave bringing a cold front down into the southern Plains, which
may introduce some rain chances, but this feature will be monitored
as the week progresses.

.AVIATION...
(06Z TAFS)
Issued at 1248 AM CDT Sun Jul 11 2021

Line of showers and thunderstorms along the Red River at 6Z may
affect KABI towards or after 11Z. There may a few storms mid to
late morning to affect KSJT and KBBD. Additional convection may
pop up mid afternoon across the terminals. Very heavy rainfall may
lower visibilities down to less than 3 miles at times during
storms. MVFR stratus otherwise will move north from the Hill
Country and TransPecos, affecting terminals except KABI through
mid morning.
